To (all whom, t Tita/y concern: j

Be it known that I, V/'ILLIAM C. Human DINGER, a resident of Louisville,in the county of Jefferson and State of Kentucky, have inventedcertain'new and useful Improvements in Safety-R aZors; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the artto which itapper- I plate, andthe wingsthereof will fulcrum on tains to make anduse the same.v i

My inventlon relates to improvements 1n safety-razors, the object of theinvention loeing to provide an improved fieXible guard and means foradjusting the same to vary its position with relation to the blade orblades,

and, further, to so construct-the blade as to #facilitate suchadjustment of the guard.

VWith thesefand otherobjeets in view the invention consists'V in certainnovel features of after appear.

.construction and combinations and arrangements of parts, as will bemore fully herein after described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is' a view in longitudinalsection, illustrating' my Fig. 2 isa view in side eleva- Fig. 4 is aplan view of the guard. Y

1 represents a sleeve having a' double 'guard 12 integral therewith andthe wings of said guard grooved or otherwise thinned, as

.shown at"3, to give" elasticity and flexibility to the wings for apurpose which herein- 4 represents the backing-plate, which is ofsufficient thickness to insure its rigidity and is secured lat itscenter to an angular rodv 5, which projects through the angular bore ofsleeve 1. A holding-sleeve 6 has angularopenings to receive the rod 5,and-the latter is screw-threaded at its end tojreceive 'a thumb-nut', 7.Sleeves 1 and have cylindricall Shanks 8 and 9, respectively, toreceive an adjusting-sleeve 1Q, and the shank 9 hasI screw-threadsmeshing with `threads in sleeve 10, so that when the latter is turnedthe guard 2 and backing-plate l will be separated ory moved towardeachpther, as the case may be.

11 represents my-improved blade, two of which'are employed with therazor. The

blade is madeA with a fiat side and tapers from the center of its'otherside down to its edges.

' In other words, the blade in cross-section is triangular,` and such.triangularfshape in cross-section providesv a fiat side to rest againstthe flat face of backing-plate'4 .and

the highest orthickest portion of the blades to swing the'guard-ngers'away from the blade edge,- as shown in Fig. 2, ready for ay closeshave. At either adjustment Vthe fiat portions of the guard rest againstfiat faces ofthe blades, and the blades are securely clamped at eitheradjustment. X

To prevent lateral movement of the blades J the backing-plate 4 isprovided with lugs 12, which latter also serve toflimit'inward movementof lugs 11a at the ends of the blades, `.and to prevent accidentaldisplacement of the blades while assembling the parts either thebacking-plate or guard is magnetized, so Vas to attract and hold thelight blade and prevent its slipping out of place beforeit can besecurely clamped.

lmade-in the general form and arrangement of the parts described Withoutdeparting from my invention,- and hence Lwouldhave it understood that Ido not restrict myself to the precise details set forth, but considermyself at liberty to make such slight changes and alterations as fairlyfall within the spirit and scope of my invention.

Having fully described my invention, what I. claim asnew, and desire tosecure by Let 'ters Patent, is-

- 1.4 A blade for a safety-razor having a fiat bearingface on one sideand the other `side having inclined faces terminating at the edges ofthe blade, vin combination with a yielding guard to receive'the side ofthev A great many slight changes might be IOO tion with a yielding guardto receive the'- Y yside of the blade having the inclined faces and anadjustable backing-plate tol 'bear against the fiat face of the blade.

y Q 3. In ansafety-razor, the coinbinaton of a `rigid backing-plate,'aexible guard and a.

" on the other side.

blade held between and said rigid backing-vplate and flexible guardf"said blade having two beveled faces onone side and-,aflat face 4. lIn asafety-razor, thecombination of' a rigid backing-plate, a blade having aflat face against the' baoking-plate, a flexible guard,

and said blade having a ulcrumon which the guard is movable 5. Inasafety-razor, the combination of a clamp for razor-blades, comprisingarigid backing-plate and a exible and elasticl guard and a razor-bladelocated between said backing-plate and guard and having a ful# 6. In asafety-razor, the combination of a` I I y double guard lhaving thinportions to' give flexibility andfelastioity thereto, a rigid doublebacking-plate,. and blades securely rod secured to the backing andl(damned between Athe guardfand backingplate, said `blades havingulcrum"on ysaid guard. v v ,I

7. The combination with a sleeve and a guard thereon, of abacking-plate, an angular roj ec ting through the guard-sleeve, a holing-sleeve having angularopenings toreceive the rod, a nut screwed ontothe rod against said sleeve,

.and an adjusting-sleevehaving screw-threaded engagement with theholding-sleeve,- and4 bearing at its other end against the guardsleeve.4 In testimony .whereof I have signed this specification in the presenceof two subscrib-
